Yintoni iRing network redundancy?

Inethiwekhi yeringi isebenzisa iringi eqhubekayo ukudibanisa isixhobo ngasinye.Iqinisekisa ukuba isignali ethunyelwe sisixhobo esinye inokubonwa zizo zonke ezinye izixhobo kwiringi.I-ring network redundancy ibhekiselele ekubeni iswitshi iyayixhasa inethiwekhi xa uqhagamshelo lwentambo luphazamisekile.Utshintshi lufumana olu lwazi kwaye luvule i-port yayo yokugcina ukubuyisela ukusebenza okuqhelekileyo konxibelelwano lwenethiwekhi.Ngexesha elifanayo, ukutshintshela kunye namachweba 7 kunye ne-8 anqanyuliwe kwinethiwekhi, i-relay ivaliwe, kwaye ukukhanya kwesalathisi kuthumela i-alamu yobuxoki kumsebenzisi.Emva kokuba ikhebula lilungiswe ngokuqhelekileyo, umsebenzi we-relay kunye nokukhanya kwesalathisi ukubuyela kwisimo esiqhelekileyo.

Ngamafutshane, iteknoloji ye-Ethernet ring redundancy inokwenza enye ikhonkco yonxibelelwano echanekileyo xa ikhonkco lonxibelelwano lusilela, oluphucula kakhulu ukuthembeka konxibelelwano lwenethiwekhi.

Yintoni i-IP protocol?

Iprotocol ye-IP yiprothokholi eyenzelwe uthungelwano lwekhompyuter ukunxibelelana nabanye.Kwi-Intanethi, yiseti yemithetho eyenza ukuba zonke iinethiwekhi zekhompyuter eziqhagamshelwe kwi-Intanethi zinxibelelane, kwaye icacisa imigaqo ekufuneka iikhompyuter ziyithobele xa zinxibelelana kwi-Intanethi.Iinkqubo zeKhompyutha eziveliswa nguye nawuphi na umenzi unokunxibelelana ne-Intanethi ukuba nje zithobela iprotocol ye-IP.Iinkqubo zenethiwekhi kunye nezixhobo eziveliswa ngabavelisi abahlukeneyo, njenge-Ethernet, i-packet-switching networks, njl., ayikwazi ukunxibelelana.Ifomathi yahlukile.Iprotocol ye-IP eneneni yiseti yeprotocol yesoftware eyenziwe ziinkqubo zesoftware.Iguqula ngokufanayo "iifomathi" ezahlukeneyo zibe yifomathi ye "IP datagram".Le nguqulelo yenye yezona zinto zibalulekileyo kwi-Intanethi, eyenza zonke iintlobo zekhompyuter zifezekise ukusebenzisana kwi-Intanethi, ineempawu "zokuvula".Kungenxa kanye yeprothokholi ye-IP ethe i-Intanethi iphuhliswe ngokukhawuleza yaba yeyona nethiwekhi inkulu yehlabathi, evulekileyo yonxibelelwano lwekhompyuter.Ngoko ke, iprotocol ye-IP nayo ingabizwa ngokuba yi "Internet Protocol".

Idilesi ye-IP

Kukho kwakhona umxholo obaluleke kakhulu kwi-protocol ye-IP, oko kukuthi, idilesi ekhethekileyo ichazwe kwikhompyutheni nganye kunye nezinye izixhobo kwi-Intanethi, ebizwa ngokuthi "idilesi ye-IP".Ngenxa yale dilesi ikhethekileyo, kuqinisekiswa ukuba xa umsebenzisi esebenza kwikhompyutha enenethiwekhi, unokukhetha ngokufanelekileyo nangokufanelekileyo into ayifunayo kumawaka eekhompyuter.

Iidilesi ze-IP zifana needilesi zethu zasekhaya, ukuba ubhalela umntu ileta, kufuneka wazi idilesi yakhe ukuze unoposi akwazi ukuhambisa ileta.Ikhompyutha ithumela umyalezo onjengonoposi, kufuneka yazi “idilesi yasekhaya” ekhethekileyo ukuze ingasi loo leta kumntu ongafanelekanga.Kuphela nje ukuba idilesi yethu ibonakaliswe ngamagama, kwaye idilesi yekhompyutheni ibonakaliswe ngamanani okubini.

Idilesi ye-IP isetyenziselwa ukunika inombolo kwikhompyuter kwi-Intanethi.Into ebonwa ngumntu yonke imihla kukuba yonke iPC edityanisiweyo idinga idilesi ye-IP ukunxibelelana ngokuqhelekileyo.Sinokuthelekisa "ikhompyutheni yomntu" kunye "nefowuni", ngoko "idilesi ye-IP" ilingana ne "inombolo yomnxeba", kwaye i-router kwi-Intanethi ilingana ne "switch controlled control" kwi-bureau ye-telecommunication.
